== History == This bridge is depicted on William Cuningham's map of Norwich drawn up in 1558.<ref>{{Cite book |title=Norwich since 1550 |date=2004 |publisher=Hambledon & London |isbn=978-1-85285-450-8 |editor-last=Rawcliffe |editor-first=Carole |location=London; New York |page=6 |editor-last2=Wilson |editor-first2=Richard |editor-last3=Clark |editor-first3=Christine}}</ref>

In 1804, the bridge was designed by James Frost, of St Faith's Lane, at a cost of £1,100.<ref name="labrum" /> It was some of Frost's early work.<ref>{{Cite book |title=A Biographical Dictionary of Civil Engineers in Great Britain and Ireland: 1500–1830 |date= |publisher=Thomas Telford |year=2002 |isbn= |editor-last=Skempton |editor-first=Alec |location=}}</ref> In the ''Norwich Mercury'', the novel principles of the bridge's construction were praised.<ref name="pevsner" /> It carried the traffic of the adjacent brewery, which is now defunct, as well as traders on Coslany Street.<ref name="labrum" />

In 1912, the bridge survived a large flood in Norwich which reached the bridge's parapets. It was later restored, and paved in brick. Since, the area has largely become residential, with the bridge's use being restricted to pedestrians and cyclists.<ref name="labrum" />

== Architecture == The bridge made up of a single cast iron span of {{cvt|36|ft|2|in|0}}, supported by four cast iron ribs that split up 5 bolted sections with solid spandrels.<ref name="labrum" /> It has simple parapet rails and panelled sides, with stone abutments.<ref name="historicengland" /> The centre panel on the outer face of both parapets features the city arms on embossed plaques, with the date 1804 cast marked at the centre of the arch. The west parapet has a projecting spout for hoses.<ref name="labrum" />
